SAFETY-INKSTAND.

Specication of Letters Patent.

Patented June 12, 1906.

Application led May 1,1905. Serial No. 258,351.

To a/ZZ whom, it may concern:

Be it known that I, BLAISE BUEFARD, a citizen of the Republic of France, residing at 11 Rue de Cluny, Paris, France, have invented new and useful Improvements in Safety-Inkstands, of which the following is a. specification.

The present invention has for its object an inkstand so constructed that it can be turned over in any direction without any of the ink it contains escaping.

The construction which makes it impossible for the ink to escape consists in principle of a disk pierced at its center by an opening, which disk can slide freely between the upper surfaces of the vessel and a retaining-cap, also perforated in the center. The disk and the surfaces between which it slides are curved in such a way as to bring their lowest point into the aXis of the inkstand, with thel result that when the inkstand is in a horizontal position the disk will automatically by the action of its own weight come into the required osition with its openin opposite those of t e vessel andl the cap; ut immediately the inkstand is inclined to one side the disk slips, moves downward by reason of its weight, and its unperforated portion covers the opening in the vessel, thus making the escape of the ink contained inthis latter impossible.

The accompanying drawings show as representative examples two forms of construction of the invention.

Figure l is a longitudinal section throu h its axis of the first form of construction, t e inkstand being represented in its normal horizontal position. Fi 2 is a similar section representing the stand lying on its side. Fig. 3 is a front elevation corresponding to Fig. 2. Figs. 4, 5, and 6 represent the same views of a second form of construction.

In the example of Figs. 1, 2, and 3, a is the vessel, made of glass or any other material, of which the upper surface b is hollowed into the shape of a spherical cup. This cup in the example of Figs. 5 and 6, where the inkstand is made of metal, is made in a separate piece screwed into the vessel itself a.

c is the retaining-cap, which forms by its lower surface d a cover concentric with the cup and leaves by means of a lower edge e, Fig. 1, or by means of a projection f Fig. 4, from the cup b a space g between this latter and the'cap c. The height of this space corresponds to the thickness of the disk 7L. This disk is pierced by an opening fi, which normally is o posits the orifices j and 7c of the vessel and t e cap.

The cap c is retained by a ring m, which can be fastened by a bayonet-joint onto a ring n of the vessel, Figs. 1 and 2. The cap c can also be fastened directly by a screw o onto the projection f of the cup t, Figs. 4 and 5.

It is easy to see that if the inkstand is inclined, Figs. 2 and 5, the disk moving down by its own weight will close with its unperforated portion the opening of the vessel, while its own openingi comes opposite an unperforated portion of the vessel. Even if the inkstand is turned completely over the disk cannot rise, but will remain against the edge of the lcap and close the vessel.

The details of construction, ornamentation, shape of the vessel or support for this latter can of course be varied without altering the principle of the invention. The disk h can be made of glass, crystal, earthenware, metal, or any other suitable material and can slip between a vessel and acap made of the same substance or of different materials.

I claim- 1. A safety-inkstand comprising an inkcontaining chamber having a concave spherical upper surface, a cap the under surface of which is convex and parallel to the concave surface and a disk adapted to fit between the spherical surfaces with freedom of movement along the surfaces, the two spherical surfaces and the disk having central apertures the dimensions being such that when the disk is most eccentric to the cover the aperture in the under cover will be closed by the disk.

2. A safety-inkstand com rising an inkcontaining chamber, a doub e cover formed with two parallel spherical surfaces and a disk adapted to fit between the spherical surfaces with freedom of movement along In testimony Wheieof I have signed my the surface, the double cover and the disk name to this specification in the presence of having central apertures, the upper surface two subscribing Witnesses.
